Description
Technical field
This utility model relates to mechanical field, particularly relates to a kind of bad water clean cycle system of silk screen printing and production line thereof.
Background technology
Crystal silicon solar back of the body electric field, back electrode are positioned at rear surface of solar cell, form the back side and the bottom electrode of silion cell.Match with the upper electrode on silion cell surface, play the effect that the electric energy that silicon solar cell produces is sent to the external world, anelectrode and back electrode and formed by printing, drying, sintering by aluminium paste by silver slurry, back electrode.
In normal cell piece silk screen printing production process; some silk screen printing substandard products caused owing to printing exception often occur, these substandard products mainly have that front description is imperfect, back side figure is imperfect, back side aluminium paste has drained to the front or side etc. of cell piece.All these printing substandard products are once through drying, after sintering, and the slight substandard products such as become, serious directly can produce waste product, thus having influence on final conforming product rate and conversion ratio.
Processing method to cell piece silk screen printing substandard products is that artificial water is carried out or rinses at all at present, and efficiency is low, weak effect, is unfavorable for the production needs of industrialization.
Utility model patent if notification number is CN203536461U discloses a kind of workbench for wiping silk screen printing substandard products, including desktop, arrange on the table for place and adsorb printing substandard products hollow table top, for supporting desktop support and for make in table top produce negative pressure so that adsorb printing substandard products vacuum pump, the panel of described table top is provided with multiple aperture, described table top base plate is provided with through hole, and described through hole is connected with vacuum pump by flexible pipe.When adopting this workbench wiping silk screen printing substandard products, silver slurry is not easy to be stained with on left handed gloves, and convenient silver slurry reclaims；And the fixing ratio of silicon chip is stronger, improves work efficiency.This patent adopts pure manual cleaning method, has cleaning efficiency low, and weak effect is unfavorable for the production needs of industrialization.
And for example notification number is that the utility model patent of CN102437234B discloses a kind of solar battery sheet printing and does over again the processing method of substandard products, solar battery sheet of doing over again carries out ultrasonic waves for cleaning, first time washing successively, hot hydrochloric acid cleans, second time is washed, dried and re-start silk screen printing, it solves the solar battery sheet after existing printing and can not effectively do over again the problem processed and cause the wasting of resources, cost increase.But it does not relate to the equipment that cell piece cleans, and cannot realize the cleaning of automatization yet, have cleaning efficiency low, weak effect is unfavorable for the production needs of industrialization.
For another example notification number is that the utility model patent of CN100505334B discloses substandard products reworking method after a kind of crystal silicon solar cell sheet printing, including three steps: with HCL cleanout fluid, remove the aluminium paste at the cell piece back side；The silver slurry of positive and negative two of cell piece is removed with isopropanol；With degree of depth cleanout fluid, the cell piece substantially removing slurry is carried out degree of depth cleaning, thoroughly wash small impurity.By the process of the method, the conversion efficiency of cell piece can reach the level of normal battery sheet, and outward appearance is also as good as with normal battery sheet, has reached the purpose cleaned of doing over again.The disqualification rate of cell piece silk-screen is reduced to about 0.2% by original about 2%, thus improve qualification rate and the yield rate of silicon solar cell.But it is also without relating to the equipment that cell piece cleans, and also cannot realize the cleaning of automatization, have cleaning efficiency low, weak effect is unfavorable for the production needs of industrialization.
